Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Han in view of Hwang et al. (US Pub. No. 2021/0126066 A1), hereafter referred to as Hwang. As to claim 16, Han discloses the light emitting display apparatus according to claim 14 (paragraphs above), Han does not disclose wherein the touch line overlaps at least a part of the second pattern. Nonetheless, Hwang discloses a similar display apparatus with a touch line overlapping at least a part of a second pattern (fig 9, touch line Y-TE extending to Y-TP). It would have been obvious to one of ordinary skill in the art at the time the application was effectively filed to form the touch line of Han overlapping at least a part of the second pattern as taught by Hwang such that the touch line can make improved electrical contact to a pad region on the substrate. Claim(s) 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Han in view of Bang et al. (US Pub. No. 2021/0134928 A1), hereafter referred to as Bang. As to claim 20, Han discloses the light emitting display apparatus according to claim 19 (paragraphs above). Han does not disclose wherein the driving circuit includes at least one MUX, and ESD circuit, a VDD line, or a VSS line, and wherein the first pattern, the second pattern, and the dam are disposed between the active area and the MUX, the ESD circuit, the VDD line, or the VSS line. Nonetheless, Bang discloses wherein a driving circuit includes at least one MUX, and ESD circuit, a VDD line, or a VSS line, and wherein a first pattern, a second pattern, and a dam are disposed between the active area and the MUX, the ESD circuit, the VDD line, or the VSS line (figs 1 and 5, VSS line and VDD line 10 and 20 disposed with first pattern 130, second pattern 110 and dam 120 between DA and VSS/VDD 10/20). It would have been obvious to one of ordinary skill in the art at the time the application was effectively filed to include the first pattern, second pattern and dam of Han between the display area and the VSS/VDD lines as taught by Bang since this will ensure that the organic encapsulation material does not overflow to the pad regions. Response to Arguments Applicant's arguments filed 2/9/2026 have been fully considered but they are not persuasive. Applicant argued that: “Han discloses that, in the second barrier PW2, a height of a topmost surface contacting the thin film encapsulation layer 300 is disposed lower than a height of a topmost surface contacting the thin film encapsulation layer 400 in the first barrier PW 1.” Examiner disagrees because the topmost surface of PW2 contacting 300 is higher than topmost surface of PW1 contacting 300. Additionally, the Han reference does not include reference number 400, it appears that 400 is meant to recite 300. Applicant argued that Han fails to disclose a configuration in which a height of a bottom surface of the first barrier is higher than a height of a topmost surface of the second barrier contacting the thin film encapsulation layer 300. Examiner disagrees because, as detailed in the office action above, Han does anticipate this limitation. Pertinent Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US Pub. No. 2021/0202895 A1.
